A destination trailer is basically the same quality and built the same as a camper but not typically pulled from site to site. Wildwood Lodges, Salem Villa, Cedar Creek Cottages, Puma has a line as well as many others.
The biggest difference we have noticed is there is very little to no basement storage. Ours does not sit permanently on a site so our water hoses, sewer hose etc. are stored in totes.
The weight is the same as our 5th wheel was at around 11K - 12K so if I want I could pull it home, but it is 42 feet long.
In Virginia a mobile home becomes real property when you remove the tongue and set it up on your land. I have noticed the on destination trailers a bolt on tongue is optional.
